Since Cocos2d-x 3.0, we have refactored the event dispatching system. cc.registerTargetedDelegate and all layer’s event functions have been deprecated. So you should migrate your implementation with the new event dispatching system.

If you want to upgrade your usb project with the newest Cocos2d engine, you should download Cocos2d-JS which include Cocos2d-x 3.0 rc0 and Cocos2d-html5 3.0 alpha: Download link

In the download package, you can find the test cases shared by html5 and jsb. The test case jsb project can be found in the folder build, and you will find tests which shows you how to use the new event system at Event Manager Test. And the sub test PauseResumeTargetTest shows exactly what you want to do.

We recommend Cocos2d-JS 3.0 to do JSB project.
For now we didn’t have extra time and man to fix 2.x JSB problems. We have been focus on fix all these issues for Cocos2d-JS 3.0
With all new features in Cocos2d-x 3.0, fixed API incompatible issues between html5 and JSB, adopted JS style API in html5 engine, hope you can enjoy much more JSB in Cocos2d-JS !
